I see from the service manual that power to the dome light and the stop light switch come from the same place, so there is a relationship there.

I think these are likley the issue.

I would start by slowly/carefully removing the Bulkhead connectors on the firewall. Clean all the male spades using some emory cloth. Don't go over board, just knock the darkness off so the brass kind of shows. It does not need to be shiny.
Then use some Di-electric grease on the spades. This is also called 'Bulb Grease' in packets at Autozone. 3 packs should do it.
On the firewall side female spades clean then as best as you can with the emory clothe folded small to insert in the female part using care not to get the emory cloth stuck. Blow out with compressed air or "Keyboard Dust Off'. Put the connectors back together and see if that helped.

Then, the door jamb switches are hard to get too but clean them up and make sure they are solid grounded.

Something as simple as the old fuse in the fuse block. Clean the fuse lugs and put in a new fuse. The old one may be slightly bad but looks OK.
